Hindsight

Install Hindsight memory for eve:

eve add extension/hindsight

This installs @vectorize-io/hindsight-eve and writes agent/instructions/hindsight.ts for recall plus agent/hooks/hindsight.ts for retention. The package requires Node.js 24 or later.

Create a Hindsight Cloud API key and add it to the agent's environment. The API URL defaults to Hindsight Cloud, and the bank defaults to default:

HINDSIGHT_API_KEY=...HINDSIGHT_BANK_ID=my-agent

The registry creates both capability files:

import { hindsightMemory } from "@vectorize-io/hindsight-eve";
export default hindsightMemory();

import { hindsightRetainHook } from "@vectorize-io/hindsight-eve";
export default hindsightRetainHook();

Before each turn, the dynamic instructions resolver recalls the user's ambient profile and working context. After the turn, the hook retains the user message and assistant reply. Neither path depends on the model choosing to call a tool.

Recall uses a fixed broad query rather than the live user message. Tune the profile context and response budget in the instructions file when needed:

import { hindsightMemory } from "@vectorize-io/hindsight-eve";
export default hindsightMemory({  recallQuery: "user preferences, identity, projects, and working context",  budget: "high",  maxTokens: 2048,});

For a self-hosted server, set HINDSIGHT_API_URL and pass apiKey: null to both factories when the server has no authentication. Other shared options include bankId, context, includeAssistantReply, timeoutMs, and onError.

A bank is one isolated memory store, and both files must use the same bank. Do not share the default bank across untrusted users; use separate agent deployments with distinct HINDSIGHT_BANK_ID values for separate users or tenants. See the Hindsight eve integration guide for Cloud, self-hosted, and factory configuration.
